Gas vacuoles occur in blue-green bacteria and in purple and green photosynthetic bacteria. They are distinct from the non-membrane-bound granules that store reserve materials.
Ref: NCERT Class 11 Biology Chapter 8: Cell: The Unit of Life Prokaryotic Cell - Structure and Components
Chromatophores are membranous extensions into the cytoplasm of some prokaryotes, such as cyanobacteria. These structures contain pigments.

Cyanobacterial colonies are generally surrounded by a gelatinous sheath and often form blooms in polluted water bodies. Cyanobacteria may be unicellular, colonial or filamentous.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Bacteria - Structure and Economic Importance
The features identify cyanobacteria. Cyanobacteria are photosynthetic prokaryotes containing chlorophyll a. Forms such as Nostoc and Anabaena may fix atmospheric nitrogen in specialised cells called heterocysts.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Bacteria - Structure and Economic Importance
Cyanobacteria are photosynthetic prokaryotes containing chlorophyll a. They may be unicellular, colonial or filamentous, and their colonies are generally surrounded by a gelatinous sheath. Some forms also fix atmospheric nitrogen in heterocysts.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Bacteria - Structure and Economic Importance
Cyanobacteria possess chlorophyll a, similar to green plants, and are therefore photosynthetic autotrophs. They may occur as unicellular, colonial or filamentous forms.
Ref: NCERT Class 11 Biology Chapter 2: Biological Classification Bacteria - Structure and Economic Importance
Cyanobacteria are prokaryotic members of Kingdom Monera and therefore do not possess a well-defined nucleus. Some forms, such as Nostoc and Anabaena, fix atmospheric nitrogen in specialised cells called heterocysts.

Cyanobacteria reflects key principle in quiz on section b solved pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Cyanobacteria aligns with experimental and theoretical evidence from population genetics, behavioral ecology and molecular phylogeny. Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why Cyanobacteria fits helps integrate natural selection, environment.
